 Abstract
The proposed model of operational management aims to treat simultaneously the reliability of the equipment, the process of maintenance and the operational costs. The continuous production of pulp is supported by practices of best sourcing developed by the back-office of the operational management using the in-sourcing and the outsourcing of the front-office so that they can add more value to the Organization through the lower cost. Thus, it is presented an operational model that integrates three different dimensions based on the information collected from the repairing orders and the operational circumstances where they occurred. One of the dimensions determines the factors that have more influence on the risk of damage and the non-availability of the equipment; the other one dimensions the teams dedicated in regimen of in-sourcing and their competences for the daily attendance of the reactive repairs using, if necessary, the failure maintenance and the proactive necessities in result of the on-line or off-line surveys made to the equipment; finally, the third dimension of the model aims at the planned subcontracting of teams in regimen of outsourcing for the simultaneous attendance of a minimum and maximum set of equipment in failure waiting for a manufacturing stop for a perfect maintenance.

 Rezumat
Modelul de management operaţional propus urmăreşte să trateze simultan fiabilitatea echipamentelor, procesul de mentenanţă şi costurile operaţionale. Este prezentat un model operaţional ce integrează trei dimensiuni diferite bazate pe informaţia colectată din ordinele de reparaţie şi circumstanţele operaţionale în care au apărut. Una dintre dimensiuni determină factorii ce au mai multă influenţă asupra riscului de avarie şi de ne-disponibilitatea echipamentului; cea de a doua dimensionează echipele dedicate în regime de "in-sourcing"; în fine, a treia dimensiune a modelului urmăreşte subcontractările planificate ale echipelor în regim de "outsourcing".
